Freezes turns white then turns off then back on

Horizontal scan output fault. Check the connections to the deflection yoke from the main board. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

There are defects in the board due to leaky or dry capacitors. This might need attention by a qualified service technician.

Hello Dsidneysis,
It appears that this failure could be in the power supply due to swelling/ bulging capacitors in the power supply.
Check the link below to find parts to fix your TV.

The problem is a defective LCD Panel.

you have to replace the vertical sweep IC and check the voltage across its VCC. If you cant understand tech words, better visit the service center.

This Problem is usually caused by Leaky Capacitors in Vertical deflection circuit.
If you are handy with electronics,
Get a can of FREEZE Aerosol.
Open the Back Cover.
Put a mirror in front of TV.
Locate the Vertical Circuit.
Turn the TV on.
Spray FREEZE on top of individual Capacitor to see if it corrects the problem.
If it does, Replace that Capacitor.

Howdy,
It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thanks for using FIXYA, big IRISH.

Greetings caesar975,

Unfortunately if you chose to view the non HD channels in wide screen format, you are going to have the top and bottom of the screen cut off. Eventually this will not be a problem when everything goes to digital. However presently non HD channels are presented in 3:2 ratio where as HD is 16:9, So your choice really is to view them with the lines on either side for now.

I do not have an answer for the white flickering lines.

To get the BEST picture out of your 1080p unit I highly recommend using HDMI cables to hook it up.

I hope some of this helps.

Sincerely,

Dorothy
